A sample driver produces driver health protocol. This driver use DiskIO driver as a template. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9516 6f19259b-4bc3-4df7-8a09-765794883524

/** @file
DiskIo driver that lays on every BlockIo protocol in the system.
DiskIo converts a block oriented device to a byte oriented device.
Disk access may have to handle unaligned request about sector boundaries.
There are three cases:
UnderRun - The first byte is not on a sector boundary or the read request is
less than a sector in length.
Aligned - A read of N contiguous sectors.
OverRun - The last byte is not on a sector boundary.

Retrieves the health status of a controller in the platform. This function can also
optionally return warning messages, error messages, and a set of HII Forms that may
be repair a controller that is not proper configured.
@param This A pointer to the EFI_DRIVER_HEALTH_PROTOCOL instance.
@param ControllerHandle The handle of the controller to retrieve the health status
on. This is an optional parameter that may be NULL. If
this parameter is NULL, then the value of ChildHandle is
ignored, and the combined health status of all the devices
that the driver is managing is returned.
@param ChildHandle The handle of the child controller to retrieve the health
status on. This is an optional parameter that may be NULL.
This parameter is ignored of ControllerHandle is NULL. It
will be NULL for device drivers. It will also be NULL for
bus drivers when an attempt is made to collect the health
status of the bus controller. If will not be NULL when an
attempt is made to collect the health status for a child
controller produced by the driver.
@param HealthStatus A pointer to the health status that is returned by this
function. This is an optional parameter that may be NULL.
This parameter is ignored of ControllerHandle is NULL.
The health status for the controller specified by
ControllerHandle and ChildHandle is returned.
@param MessageList A pointer to an array of warning or error messages associated
with the controller specified by ControllerHandle and
ChildHandle. This is an optional parameter that may be NULL.
MessageList is allocated by this function with the EFI Boot
Service AllocatePool(), and it is the caller's responsibility
to free MessageList with the EFI Boot Service FreePool().
Each message is specified by tuple of an EFI_HII_HANDLE and
an EFI_STRING_ID. The array of messages is terminated by tuple
containing a EFI_HII_HANDLE with a value of NULL. The
EFI_HII_STRING_PROTOCOL.GetString() function can be used to
retrieve the warning or error message as a Null-terminated
Unicode string in a specific language. Messages may be
returned for any of the HealthStatus values except
EfiDriverHealthStatusReconnectRequired and
EfiDriverHealthStatusRebootRequired.
@param FormHiiHandle A pointer to the HII handle for an HII form associated with the
controller specified by ControllerHandle and ChildHandle.
This is an optional parameter that may be NULL. An HII form
is specified by a combination of an EFI_HII_HANDLE and an
EFI_GUID that identifies the Form Set GUID. The
EFI_FORM_BROWSER2_PROTOCOL.SendForm() function can be used
to display and allow the user to make configuration changes
to the HII Form. An HII form may only be returned with a
HealthStatus value of EfiDriverHealthStatusConfigurationRequired.

managed by this driver specified by This have a health
status of EfiDriverHealthStatusHealthy with no warning
messages to be returned. The ChildHandle, HealthStatus,

controllers managed by this driver specified by This
do not have a health status of EfiDriverHealthStatusHealthy.
The ChildHandle, HealthStatus, MessageList, and
FormList parameters are ignored.
@retval EFI_DEVICE_ERROR ControllerHandle is NULL, and one or more of the
controllers managed by this driver specified by This
have one or more warning and/or error messages.
The ChildHandle, HealthStatus, MessageList, and
FormList parameters are ignored.
